Water line leaking in crawlspace upon arrival. Customer stated that he could hear the water running in the crawl space. After looking found 3/4 pvc cracked and leaking at a ball valve. Informed customer we could repair the line and add another ball valve. Gave customer estimate, customer approved estimate. Repaired section of pipe and installed a new ball valve. Turned water back on to check for leaks and found no leaks. Left ball valve off because the previous one was off. No leaks upon departure
